SUSE CVE-2026-71851

crypto-js is a JavaScript library of crypto standards. Versions of crypto-js prior to 4.0.0 generate randomness in CryptoJS.lib.WordArray.random using a custom variation of the Multiply-With-Carry pseudorandom number generator, seeded from Math.random, instead of a cryptographically secure source...

CVE-2026-73567 sm-crypto: Predictable SM2 key generation in Node.js: default RNG uses Math.random + wall clock

sm-crypto provides JavaScript implementations of the Chinese cryptographic algorithms SM2, SM3, and SM4. Prior to 0.5.0, the default no-argument sm2.generateKeyPairHex path in Node.js uses the module-wide SecureRandom instance in src/sm2/utils.js, supplied by [email protected], which seeds an ARC4 strea...

CVE-2026-73567

Summary: The vulnerability affects the sm-crypto library (SM2/SM3/SM4) prior to version 0.5.0. The default Node.js key generation path for sm2.generateKeyPairHex() relied on a module-wide SecureRandom seeded from Math.random() and Date to an ARC4 stream because window.crypto.getRandomValues was u...

Insufficient Entropy in PRNG

Overview epetherpad-lite is a modern really-real-time collaborative document editor. Affected versions of this package are vulnerable to Insufficient Entropy in PRNG through the ImportHandler and ExportHandler in src/node/handler/ImportHandler.ts and src/node/handler/ExportHandler.ts. An attacker...

form-data uses unsafe random function in form-data for choosing boundary

Summary form-data uses Math.random to select a boundary value for multipart form-encoded data. This can lead to a security issue if an attacker: 1. can observe other values produced by Math.random in the target application, and 2. can control one field of a request made using form-data Because th...

Predictable Boundary Selection

Undici is vulnerable to predictable boundary selection. The vulnerability is due to the use of Math.random to choose the boundary, which can be predicted if several of its values are known, potentially allowing an attacker to tamper with requests to backend APIs...

CVE-2025-22150

Undici is an HTTP/1.1 client. Starting in version 4.5.0 and prior to versions 5.28.5, 6.21.1, and 7.2.3, undici uses "Math.random" to choose the boundary for a multipart/form-data request. It is known that the output of "Math.random" can be predicted if several of its generated values are known. ...
